To all whom it may concern:

Be it known that I, HENRY W. PLEISTER, a citizen of the United States, residinsg in Westfield, in the county of Union and tate of New Jersey, have invented certain new and useful Improvements in Conduit or Cable Clamps and Bridle-Rings, of which the following is a specification, taken in connection with the accompanying drawings.

My invention relates to the combination of a conduit or cable clamp and a bridle ring, and also to a cable or conduit clamp and a bridle ring as sub-combinations of the main combination, and as articles of manufacture.

My invention further relates to a cable or conduit clamp, which can be manufactured at minimum expense and to which a bridle ring may be secured either at the original installation of the cable and conduit clamp, or at any future time when it may be desirable to support one or more runs of bridle wires.

My invention further relates to a conduit or cable clamp provided with a vertical stirrup into which the locking hook of a pigtail bridle ring is hooked and from which it is suspended.

My invention further relates to such a conduit or cable clamp having not only the vertical stirrup but in addition a projection or catch on the base to engage with the bridle ring and prevent its rocking or swinging in the stirrup.

My invention further relates to a conduit or cable clamp which is preferably formed out of pressed sheet material, as pressed steel, or which may be formed from castings of malleable iron, brass, an alloy, aluminum or any other metal.

My invention further relates to certain combinations, sub-combinations, articles of manufacture, and details of construction, all of which will be more fully hereinafter described and pointed out in the claims.

In the figures, in which I have shown different embodiments of my invention, the same reference numerals refer to similar parts in the several figures.

In the commercial use of conduit or cable clamps it is not generally possible, at the of the original installation, to determine whether or not bridle rings will be needed to support additional loose strands of bridle wires. In commercial practice, a cable is supported on a Wall or othersuitable support and it may be weeks, months, or years later that the telephone'engineers will determine that it is desirable to support bridle wires parallel to the cable.

By my invention my original conduit or cable clamp may be used as a separate article of manufacture or sub-combination, and then later, when the needs of the service demand it, my bridle ring may be supported by the same conduit or cable clamp, when the complete combination would'be used.

In my invention I forma conduit or cable clamp with a vertical stirrup adapted to have a pigtail bridle ring hooked into it, the bridle ring hanging from the stirrup and adapted to be readily attached or detached by simple manipulation.

I have shown difierent embodiments of my invention by way of illustration, but of course my invention is not to be confined to the particular forms illustrated. I In one form I permit the bridle ring to hang loosely from the vertical stirrup so that there is more or less swing or rock to the bridle ring; excessive rocking is prevented by the runs of bridle wires 8, 8. p In other forms of my invention I provide the base with a projection or catch over which the-end of the pig tail bridle ring is pressed and which prevents this rocking or swinging of the bridle ring so that in this form the bridle ring is more or less rigidly secured after being once positioned. a In other forms I accomplish the same result without necessarily forcing the bridlering over the projection or catch.

In Figs. 1, 2, 3 and 4. I have shown a conduit or. cable clamp 1, having a hook portion 2, which contacts with and supports a conduit or cable 3, and with a'base 4, which '5, to which lies against a wall or other suitable support the conduit or cable clamp is held by the securing screw 6. I provide the base 4 with a vertical stirrup 7, which extends above the surface of the base. When the clamp is formed out of pressed sheet material which is the preferred construction, this vertical stirrup is stamped up from the base 4 as shown in Fig. 1. r V p When the conduit or, cable 3 is first inity ofthe installation without taking down stalled the bridle rin as a rule, is not employed. It is only w en the traflic load becomes excessive and the telephoneor telegraph engineers. desire to increase the capacthe cable 3 and substituting a larger cable that they accomplish the same result more economically by running bridle wires 8, 8 parallel to the cable. In my invention the bridle ring 9having the locking hook 10 and the pigtail 11 is attached to the vertical stirrup 7 by simple manipulation. In Fi 2. I have shown for. example the bridle rlng 9 in one of its attaching positions. From'the position shown in this figure the bridle ring is rotated substantially 90 and then pulled 7 down 90 until it assumes the position shown in Fig. 3. The locking hook 10 on the end of the bridle ring then engages the inner and outer surfaces of the vertical stirrup 7 and prevents the bridle ring being accidently disengaged from the stirrup. In this form the bridle ring, prior to stringing the runs of bridle wires, can rock or swing in The wires 8, 8 are mounted within the bridle ring. These runs of bridle wires limit the rocking of the bridle ring in the stirrup; and prevent the bridle ring from being swung far enough around to permit its extraction from the vertical stirrup.

In Figs. 5 and 6 I have shown a modification of my invention, in which the base i, in addition to being provided with the stir rup' 7, is provided with a catch or projection 13. When this conduit or cable clamp-is formed from pressed sheet metal, this catch or projection is stamped up from the base so that it is raised an appreciable distance from the surface of the base. of my invention I take the bridle ring 14, Fig. 7, having-thelocking hook 15, arm 16,

and pigtail 17 and attach it to the vertical.

stirrup 7 as shown in Fig. 6.. The bridle In this form ring is brought into the position shown in dotted lines in Fig. 6, and isthen swung by the projection or catch 13 engaging with the arni 16 of the bridle ring.

Rocking in theother direction is prevented byv the shank 16 engaging with theside ofthe vertical stirrup 7. V

In this form of my invention the removal of the bridle ring 14 from the vertical stirrup 7 is prevented .bythe hook 15 contacting.

withthe head of the securing screw 6.

In Figs. 8, 9, 7 little diiferent form of bridle ring. In this modification a bridle ring 19 is provided with a locking hook 20. [To position this form of the invention the looking book 20 of the bridle ring 19, Fig. 11,- is brought into the position shown-in full lines, Fig. 9. It

is then swung down 90 back of l the projection or catch 113, without necessarily passing over it, as does the bridle ring shown in Figs. 5 and 6. The projection or catch 113 in Fig.3, 9 and 10 isv raised higher above the base than is the catch 13, Figs. 5 and 6.

To release the bridle rings 1 or 19 shown in Figs. 5' to 11 inclusive, afterthebridle wires are removed it is merely necessary to raise the bridle ring so that its arm will 10 and 11 I have shownya escape the projection or catch 13 or 113,

and then reverse the operation of attaching it tothe clamp. In Figs. 8, 9 and,10the bridle ring maybe swung up vertically 90 and thenremoved, without; passing overthe projection 113. In Fig. 6 the bridle ring as to be sprung so that the arm 16 can be raised over and engage the catch or projection 13 to permit the bridle ring to move in the arc of a horizontal circle.

In all forms of my invention the pigtail bridle ring is simply hooked into the vertical stirrup and permitted to hang freely therefrom.

Having thus described this invention in connection with illustrative embodiments thereof, to the details of which I do not desire to be limited, what is claimed as new and what is desired to secure by Letters Patent is set forth in the appended claims.

WVhat I claim is I 1.
